## What it is
A cheatsheet documenting modern C++ language and library features from C++11 through C++23. It serves as a quick reference for developers learning or looking up newer C++ standards features.

## Use cases
- look up what new features C++20 introduced
- learn modern C++ language features
- find examples of C++23 library features
- quickly check C++17 syntax like structured bindings
- refresh knowledge of coroutines and concepts in C++
- compare features across C++11 to C++23 standards

## When to choose
- you need a concise reference for modern C++ standard features
- you are learning C++11/14/17/20/23 and want quick examples
- you want a curated list of what each C++ standard added

## When to avoid
- you need a full C++ tutorial or beginner course
- you need compiler-specific documentation or implementation details
- you need a searchable API reference rather than a feature cheatsheet

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation
- domain: programming-languages, tutorials, developer-tools
- platform: cpp, cross-platform
- tags: cheatsheet, cpp11, cpp14, cpp17, cpp20, cpp23, reference, language-features
